So far there are no observations of a black hole with anywhere near enough resolution to resolve this. The black sphere is called the event horizon and represents the point where, because of the huge deformations to spacetime and its causal structure, not even light could escape. This is in principle observable (though only the Milky Way's central black hole is close enough to resolve it); see e.g. this answer.
The jets, on the other hand, have mostly been observed when Earth happens to lie in their line of sight - inside the jet, and luckily quite far away! Some jets have indeed been observed in noncollinear geometries, such as the one in M87, but we do not have the resolving power, at those distances, to observe the jet's launching region. For many black holes closer in - like the central black hole in the Milky Way - we do have plenty of indirect evidence that jets exist, but it's hard to observe them directly.
